Question
What is a common application of the Abstract Data Type "Dictionary" or "Map"?a)Keeping track of elements in a LIFO manner.b)Representing a collection of elements with no duplicates.c)Storing elements in a sorted order.d)Associating keys with values for efficient retrieval.
Solution
The common application of the Abstract Data Type "Dictionary" or "Map" is d) Associating keys with values for efficient retrieval.
This is because a dictionary or map is a collection of key-value pairs where each key is unique. This structure allows for efficient retrieval of values when the key is known. For example, it can be used in a phone book application where the names of people (keys) are associated with their phone numbers (values). When you want to find the phone number of a person, you can just look up their name in the dictionary or map, instead of going through a list of all phone numbers.

A fundamental concept of dictionary is that all its keys are unique. This is used ina lot of daily scenarios. For example, your student number uniquely identifiesyou at HKU and every office at HKU can use this number to link the data aboutyou. This concept can be used to implement a database where a unique key isused to identify all the data associated with this key.We will simulate a simple university database using dictionaries. Thedictionaries in the database are linked by unique keys that can be used toidentify a specific entry in a dictionary. For example, one of the dictionaries inthe database is a timetable dictionary that contains the timetable of differentcourses where each entry contains course_ID, teacher_ID, start_time, end_timeand venue_ID. The timetable dictionary can be linked to another dictionarycalled teacher dictionary by teacher_ID. We can therefore use the teacher_IDstored in the timetable dictionary as a key to retrieve the information of thecorresponding teacher stored in the teacher dictionary
Which of the following statements does not apply to associative memories (maps)?It is allowed to assign keys twice in a map.The associative memory allows extremely fast access to the elements.The elements of a data structure implementing the interface java.util.Map can be identified by their key.Depending on the technical implementation, elements of a map can be stored in a tree structure, in a hashed table, or in a combination of hashed table and concatenated list.
